When I delete a message, I get the following error: "An error occurred while moving messages to mailbox “(null)”." What's more, the message does delete, but it doesn't end up in the trash, or anywhere for that matter - it's lost forever. Anybody know a fix?
MacBook Pro (15-inch Early 2011), OS X Yosemite (10.10)
I found a way to fix this. I assume you're using an IMAP account. If so, you should be able to expand the mail account and see the folders that exist on the server. Find the one you want to use for Trash, select it, then go to the "Mailbox" menu and find "Use This Mailbox As..." and select "Trash Mailbox". You can do the same for sent messages, junk, etc. Once I did this, the message stopped appearing.
Removing map accounts and setting them up didn't solve the issue, but right now there was an update to El Capitan and Mail.app (9.2). Hope this works.
PDJ-SF, I'm glad that worked for you. I didn't want to do this because my account is through iCloud, and deleting the Mail portion of it means disconnecting all the other iCloud services and then reconnecting them. I also figured that it would accomplish largely the same result as rebuilding the mailbox, as in Brett L's solution above.
But, I decided to go ahead and try deleting everything. The good news is that it didn't take as long as I thought it would, and after signing back in and checking all the boxes, iCloud services appear to be working. The bad news is I still get the same error message when deleting messages from my Inbox, and the message seems to be gone forever.
I finally fixed this issue on my Mac…
• Log in to Gmail using your browser
• Go to Settings
• Click on Labels
• Under System Labels –> Trash, tick the box for 'Show in IMAP'
The Trash folder in Mail –> Preferences –> (your account) –> Mailbox Behaviours –> Trash Mailbox should now be available and the (null) alert when deleting a message should be gone
…hopefully

I'm sure now this is a bug. And sorry, it's not Yosemite but El Capitan. Mail functions correctly on my iPad, same IMAP accounts. Tried the advise to rebuild the mailbox, and it doesn't work, so I'm going to try to remove all accounts and ad them again.
I started getting this error today "An error occurred while moving messages to mailbox “(null)”.
But when I try to: "Use This Mail Box As" > the options are all greyed out.
For some reason two of my mail accounts are also in the TRASH with strange Black Squares as their folder icons.
Any one else?
Thanks for any advice.
Cheers

Brett, thanks, but unfortunately that doesn't help.

With me, out my six accounts it only happens on one of them. Unfortunately the one I use the most...
Thanks, this fixed my problem.
It also help me, thanks for sharing 🙂
I know it's late to be asking this question, but when I select the mailbox and then Mailbox/UseThisMailboxAs all the mailboxes are greyed out and I can't pick any of them. 😟
This worked great for me and fixed the problem!!! Thank you @tbiske
I am in the same boat. The menu is greyed out. Anyone?
An error occurred while moving messages to mailbox “(null)”.
